A player who has steadily improved since joining from Barcelona in 2011, Jon featured 24 times across all youth competitions in 2013/14, scoring seven goals in the process.

Capable of playing in central-midfield or on either flank, Jon found the net twice in the U21 victory at home to Aston Villa and he was also on target against Borussia Dortmund and Shakhtar Donetsk in the UEFA Youth League.

Tall and a good passer of the ball, he featured for the first-team in their pre-season friendly against Boreham Wood and will be hopeful of further senior involvement this season.
